may be wheeled about from chair to chair as" occasion requires. In i conducting :hair waving operations withapparatus of the general type described, which has gone into uni,- versal and extensiveuse; it'has-been found that'i-n different loc'alitiesthere are variations the voltage of the electric current supplied and since variation in voltage re sults iin a corresponding variation in the heat :developed in the coils of the individual;

heatersfit is necessary to supply some form ofcurrerit or voltage regulating means? It. is accordingly an object ofthepresent-invention' to provide a i current regulating means as a partfofthe heaterapparatus referred to.'

The invention comprises the useuof a rheostat "coil preferably wound directly on and in insulated relation to the standardwoi post which forms a part of'the main framework ofthe heater apparatus. -A 'slidable contactunember ismounted on a conducting rod and arranged tobe' moved along the: rheostat coil to' make contact "with ditferent windings thereof in accordancewith the position" of' th'e slide with relation to the length'of the coil.

slide'is movably mountedand also includes the slide'n'iember itself and a variable number "of windings-inthe coil corresponding to the. position of the slide member thereon; A cylindrical shell" or housing surrounds the coil in spaced apart irelation'thereto and enact ta the standard or post onwhieh;

the coil is mounted in order toprovide for.

suflici'ent space or'clearance in which to mount the movable slide member. The casf ing or housing is provided with a longitudin-al slot throughwhich the slide member extends for access by the operator. The housing is' also provided with perforations in. its s de wall to provide. a ventilating or cooling action and preferably some form ofcurrent. reading device is mounted on the'upper end :of-the housing for convenience of the operator in setting the slide ito produce the desired temperature conditions in the heating devices; .7 K I 1 Other features of the invention will be hereinafter described and claimed.

In thedrawings, in which a preferred embodiment of the invention has been selected for illustration:

Referring tothedrawings for a more detailed description of the invention, in Figure '1 there is shown an electrical heater; apparatus of thetype described which includesa post .or standard 5 1nounted on a laterally, v

extending basecmember 6 provided with suit able casters or rollers Tito provide for moving theapparatus aboutfrompla ce to place. The upper end of the standard 5 is equipped, with a telescopic section 8 which terminates in a laterally extending upperi'portion Q'haw.

ing' depending therefrom a framework 10 from-whichare suspended a ser es of electrical heaters 11 used 1n treating hang The reduced section8 of the standard which is adapted; to be vertically adjusted within the lower and hollow standardsection =5 is provided with a coil 12 formed of suitable resistance wire and wound on layerz; of insulating material 13 which immediately;

ardv 8. Disk or plate memb provided r'espectively at the of the ccilli are i i surrounds-the enclosed section of the stand f 1 and 1 i l i e ar' s etr e relation to the standard 8 and provide upper and lower closure members for a housing or casing member 16 which is mounted in en closing relation to the coil 12 and the included portion of the standard or post 8. The end plate members 14 and 15 serve also to support a rod or bar 17 on which a slidable contact member 18 is mounted for move ment longitudinally of the coil 12. The slidable contact member 18 makes contact with adjacent windings of the coil 12 and thereby provides a means for varying the number of the windings of the coil 12 which are included in the circuit path of current passing through the device. For this purpose the rod or bar 17 and the coil 12 are included in part in the circuit path, the portion of operator in using the device.

It will be seen that the housing or casing 16 is mounted in an eccentric relation with respect to the coil 12 and the included section of the standard 8. The eccentricity thus produced provides for a substantial space or clearance 21 on the side of the coil 12 in which the sliding contact member 18 is arranged to operate. ing 16 is preferably provided at its upper and lower ends with openings 22 which serve to ventilate and control the temperature of the device; A switch 23 or other current controlling means is mounted on the housing at a place convenient for the operator.

Preferably a current measuring device;- such as a volt meter 21 having a Wall 25 provided with an elongated horizontal sight opening 26 therein and pointer or marker 27 movably mounted back of the sight opening, is mounted on the upper end of the casing at a-point easily read by the operator in order to assist in adjusting the position of the sliding contact member 18 to provide'the desired temperature condition in the heaters 11. No scale is provided, the attendant merely being required to take care that the marker 27 is brought into alignment with the enlargement 28 in the sight opening or slot 26.

A conductor cable 29, having a plug connector 30, is provided for connecting the heater apparatus described to any convenient wall outlet.

It will be seen that a current controlling device has thus been provided in combination with a heater apparatus of the general type described, which enables operators in different localities to procure the desired standard and constancy of temperature and to adjust the apparatus in accordance with the various voltages used in different localities in order to bring about the desired same- The housing or cas ness of temperature required for the most effective hair treating operation. By using a current regulator or voltage adjustor of the type described, variations in voltage cover ing as much as twenty-five units may be compensated for to produce the same degree of heat. The coil 12 is wound in practice to effectively operate on an apparatus employing twenty or more individual heaters 11 on current of one hundred and ten volts or thereabouts.
